Description

Film sealing instrument

Technical Field

The application relates to the technical field of medical detection, in particular to a film sealing instrument.

Background

In biological tests, a sample solution to be tested is usually added to each tube of a multi-well plate, and then the multi-well plate is placed in a test instrument to perform a reaction. However, some reactions require heating or shaking, and in order to prevent sample loss and aerosol contamination due to evaporation and leakage of the sample solution during the reaction, a thin film is heat-sealed on the porous plate, and the samples are packaged in respective tubes by a film sealing operation. At present, a film sealing instrument is mostly used for performing film sealing operation on the porous plate. The common film sealing instrument mainly comprises a semi-automatic film sealing instrument and a full-automatic film sealing instrument. Specifically, the semi-automatic film sealing instrument needs manual placement of the heat sealing film on the perforated plate by an operator, and then the film sealing instrument seals the film, so that the whole process needs participation of professional operators, the automation degree is low, the current use is less, and the semi-automatic film sealing instrument is mainly applied to a low-flux scene. The full-automatic film sealing instrument can effectively solve the problems, can realize automatic conveying of the heat sealing films, improves the automation degree of film sealing, and is widely applied at present.

In the prior art, in a full-automatic film sealing instrument, a heat sealing film is conveyed by matching a winding mechanism and an unwinding mechanism, a heat sealing film with a specific size is cut out by a film cutting structure in the conveying process, and then the heat sealing film is packaged on a porous plate by the film sealing mechanism. For example, in the patent application with the application number of CN215852271U, a rolling structure and an unreeling structure are adopted to cooperate to convey the heat-sealing film, a ring-shaped blade is adopted to cut out a square heat-sealing film from the heat-sealing film with a wider width in the conveying process, and then the square heat-sealing film is packaged on a porous plate through a film-sealing mechanism.

However, as can be seen from the above, in the prior art, since the heat-sealing film is conveyed by the winding mechanism and the unwinding mechanism, in order to ensure that the heat-sealing film can be continuously conveyed, only a wide heat-sealing film can be used, and then the heat-sealing film with a specific size is cut out by a special cutter. This results in more waste heat-seal film after the film is sealed, resulting in waste heat-seal film and a great increase in film sealing cost.

The working principle of the film sealing operation of the film sealing instrument in the application is explained in detail as follows:

after the film sealer is energized, it is first necessary to check whether the roll heat-seal film 710 is adequate, and if the roll heat-seal film 710 is insufficient, it is necessary to replace the roll heat-seal film 710 with a new one. Specifically, when the roll type heat-seal film 710 is replaced with a new one, as shown in fig. 20, the roll type heat-seal film 710 is first fixed in the U-shaped receiving space 731, and after the fixing is successful, the heat-seal film 711 on the roll type heat-seal film 710 is passed through the first roll 750, and then the heat-seal film 711 is passed through the gap between the second roll 770 and the fixing member 760. After passing through successfully, the second bracket 110 is rotated around the first bracket 130 by the handle 150, a gap is formed between the driving roller 140 and the driven roller 120 after rotation, then the heat sealing film 711 is horizontally passed through the gap between the driving roller 140 and the driven roller 120, a gap formed by passing the heat sealing film 711 through the first top plate 270 and the second top plate 280 after passing through successfully, and a gap formed between the fixed knife 240 and the movable knife 220. At the same time, the handle 150 is restored to its original position. After the above operations are completed, the replacement of the rolled heat-seal film 710 is completed.

After the replacement is completed, the film sealing instrument enters a film sealing process. Firstly, after the film sealing instrument is electrified, all parts are in an initial position (zero position); specifically, at this time, the door 910 on the housing 90 is in an open state, the second bottom plate 52 is located at the second position, the second bearing member 40 extends out of the housing 90 through the door 910, the heating assembly 60 is located at the highest position, and the heating pipe 680 starts to perform a heating operation on the heating plate 640. When the temperature sensor 662 detects that the heating plate 640 reaches the set temperature, the film sealing apparatus starts the film sealing operation.

In performing the film sealing operation, the external robot jaw grips or manually places a porous plate 41 on the second carrier member 40. Meanwhile, the first driving part 180 drives the driving roller 140 to operate, the driving roller 140 drives the driven roller 120 to operate after operating, and the driving roller 140 and the driven roller 120 convey the heat-sealing film 711 with preset length by friction force in the operating process. The heat-seal film 711 of a predetermined length is then introduced into the first carrier member 30 through the gap formed between the first top plate 270 and the second top plate 280 and through the gap formed between the stationary blade 240 and the movable blade 220. After the transfer of the heat-seal film of the preset length is successful, the first driving member 180 stops.

Then, as shown in fig. 21, the second driving member 630 drives the lifting plate 690 and the heating plate 640 to descend, and the striker 691 gradually approaches the movable blade holder 210 during the descending process. When the lifting plate 690 is lowered to a certain position, the striker 691 contacts the movable blade holder 210; after contact, striker 691 continues to descend and drives carriage 210 down. When the movable blade holder 210 is lowered to a certain position, the fixed blade 240 contacts the movable blade 220 to cut off the heat seal film 711. At the same time, the first top plate 270 is gradually lowered while the movable blade holder 210 is lowered, and when the movable blade holder 210 is lowered to a position where the movable blade 220 contacts the fixed blade 240, the first top plate 270 contacts the second top plate 280, thereby clamping the heat seal film 711. As shown in fig. 22, when the film cutting is completed, the vacuum pump generates negative pressure, and the adsorption assembly 610 adsorbs the heat-seal film 711. As shown in fig. 23, after the adsorption is successful, the second driving member 630 drives the lifting plate 690, the heating plate 640 and the heat sealing film 711 to rise, the reset sensor 661 monitors during the rising process, and when the reset sensor 661 monitors that the lifting plate 690 rises to the zero position, the second driving member 630 stops running. Meanwhile, in the process of lifting the lifting plate 690, the movable blade carrier 210 is reset under the action of the reset member 260, and is restored to the initial position.

Thereafter, as shown in fig. 24, the first driving motor 53 drives the second base plate 52 to slide, so that the second base plate 52 moves from the second position to the first position, and the door 910 is closed. Meanwhile, the first driving part 180 drives the driving roller 140 and the driven roller 120 to operate, and drives the two rollers to transfer the heat-sealing film 711 with a preset length to the first bearing part 30 by friction force after the operation, so as to prepare for the next film sealing.

Then, as shown in fig. 25, the second driving member 630 drives the heating plate 640 and the lifting plate 690 to descend, the film sealing sensor 663 monitors in the descending process, and when the bottom surface of the heating plate 640 contacts with the upper surface of the porous plate 41, the film sealing sensor 663 sends out a film sealing signal, the second driving member 630 stops running, and the heating plate 640 and the lifting plate 690 stop descending. At this time, the vacuum pump is stopped, and the adsorption assembly 610 releases the heat-seal film 711 so that the heat-seal film 711 is placed on the porous plate 41. Meanwhile, the heating plate 640 is continuously pressed down for a preset period of time to combine the heat-seal film 711 with the porous plate 41, and the film sealing operation is performed on the porous plate 41.

Then, as shown in fig. 26, the second driving member 630 drives the heating plate 640 and the lifting plate 690 to rise, so that the heating plate 640 and the porous plate 41 are separated. When the reset sensor 661 detects that the lifting plate 690 is lifted to the zero position, the second driving part 630 stops operating.

After that, as shown in fig. 27, after the film sealing is completed, the door 910 is opened, the first driving motor 53 drives the second bottom plate 52 to slide, and the second bottom plate 52 moves from the first position to the second position. The perforated plate 41 with the film sealing successfully is then removed by a robotic gripper or manually.

It should be noted that the master control device may be disposed inside the film sealing apparatus, and the film sealing process may be controlled by the master control device. Alternatively, the above-mentioned film sealing process may be completed by the user by clicking a button control on the operation panel 930.

As can be seen from the above, the present application enables the heat-sealing film to be continuously conveyed by using the roll type heat-sealing film 710 without manually adding the heat-sealing film, thereby improving the degree of intellectualization in sealing the film. Meanwhile, compared with the prior art, the heat sealing film conveying mode adopted by the application does not influence the subsequent film sealing process even if the heat sealing film is completely cut off; on the basis, the heat-sealing film can be completely cut off, so the heat-sealing film with smaller width, which can fully seal the porous plate 41, is adopted in the application, and waste heat-sealing film can not be generated after sealing, thereby saving the use of the heat-sealing film and greatly saving the cost of sealing the film.

In addition, in patent application CN217805404U, a plurality of heat-seal films 711 cut in advance are attached to a continuous carrier film at regular intervals. Although this embodiment can avoid wasting the heat-seal film 711, the cost of the film sealing is still high due to the carrier film. However, the application does not need to use a carrier film, thereby greatly saving the cost of film sealing.

The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
